OK, so... I was farming out herbs to level my mages alchemy and get jumped by a lvl 80 disc priest with 45k hp.... I am on an 88 frost DK with 201k. That priest was able to outheal all my burst with just renew and bubble, I never even got her down to 90% hp or mana, while she just ran around refreshing bubble and renew... while slowly killing me with shadow ward pain. She just kept refreshing on me to keep me in combat so I could not farm or heal other than with Death Siphon or waiting for Lichborne to come back up. Even saving all my CD's to try and burst her down while I had NS stacks on and I silenced barely broke the bubble.
On an opposite note, what is up with warlocks and omg wtf one shot 99999999999 dmg chaos bolts? I am out trying to level and all of a sudden boom, dead because a warlock lands nearby on a hill or something and one shots me.
